Wilo TWI, 4-0114-C VK-1/50, Pump Package Borehole

Description

Bridging and transporting water from a borehole submersible pump. Integrated check valve. Supplied with installed cable and wire. Incl. Condenser box for single phase. Approved for drinking water, RISE type approval SC0323-18.

Fully submersible, multistage pump for pumping industrial and potable water with radial or semi-axial impellers in sectional design for vertical or horizontal installation, with integrated non-return valve. Corrosion-free single-phase or three-phase direct-start AC motor with water-glycol filling. Hermetically molded with enamel insulation of windings, resin impregnated and self-lubricating bearings. The motor is cooled by the pumped fluid. Therefore, the device must always be submerged during operation. The maximum fluid temperature and minimum flow rate limits must be followed. Vertical installation is possible with or without a cooling jacket. For horizontal installation, a cooling jacket must always be used.
